The Hot Flashes Page

Hot Flashes.
The Data.

One minute you're fine. The next you're on fire from the inside out, drenched in sweat, wondering if this is what the rest of your life looks like. It's not. Up to 80% of menopausal women experience hot flashes. The median duration is 7.4 years. But here's what nobody tells you: the earlier they start, the longer they last. And there are things that actually work.

The numbers nobody gives you.

7.4 yrs

Median total duration of hot flashes. Not months. Years. The SWAN study followed 1,449 women over 17 years to get this number.

Avis et al., JAMA Intern Med, 2015

10.1 yrs

Median duration if hot flashes start in early perimenopause. The earlier they begin, the longer they last. This is the data nobody warns you about.

Avis et al., JAMA Intern Med, 2015

4.5 yrs

Median persistence after your final menstrual period. Even after you think it's over, they can continue for years.

Avis et al., JAMA Intern Med, 2015

3x

Women with moderate or severe hot flashes are nearly three times more likely to have sleep disturbance.

02

How long they last depends on who you are.

The SWAN study found significant differences in hot flash duration by race and ethnicity. This matters because most clinical trials have historically underrepresented Black and Hispanic women.

Black women
>10 yrs
Hispanic women
~8.9 yrs
White women
~6.5 yrs
Chinese women
~5.4 yrs
Japanese women
~4.8 yrs

Real data on hot flashes and perimenopause barely exists. Help us change that.

The bottom line.

Hot flashes are not a minor inconvenience. They last a median of 7.4 years, disrupt sleep, impair quality of life, and affect work and relationships. But they are treatable. HRT reduces them by 77%. Veozah targets the exact neurons that cause them. SSRIs and gabapentin offer alternatives for women who can't take hormones. The first step is tracking them so you can show your doctor what's actually happening. The second step is having the conversation. You deserve to.
